To all whom t may concern;

Be it known that we, CLAEs F. Roanne.V and AUGUST MALMBERG, citizens of thev United States, and residents of the city' of Chicago, county o f Cook, and State of Illinois, have invented certain' lnew and useful Improvements in Laundry Mangles, of which the following is a specification.

Ourvinvention relates to laundry mangles or pressing devices, the present application being a'division of our pending application, Serial No. 728,565, ledOotOber th, 1912, for mangles.

The obj ect of our inventionI isthe production of a machine of the character mentioned A wherein will be provided means for readily i and easily movingthe movable or padded rollers includedl in the device, outwardly or from engagement with the heatedroller, and for lock-ing said movable or padded rollers in their outer positions.

A' further object is Vthe production cfa mangleas mentioned whichkwill be of du- 'rable and economical construction and eilt' cient in use. A

Other objects will appear hereinafter; The invention consists in the combinations and arrangements of parts hereinafter' described and claimed.

The invention will be best'understood by reference to the accompanying drawing- .forming a part of this specification, and in which, Y

Figure 1 is a front elevation' of a manglev embodying our invention, the central por-4 tion thereof being broken away, Fig. l2 f is "a vertical transverse section taken on substantially line -m of Fig. 1, and Fig. 3 is an enlarged detail section taken on substantially line y-y of Fig. 2.

The preferred form of construction as illustrated in the drawing comprises two spaced upright frame members 1 the lower -v portions of which, when the machine is in use, being securely fastened to thefloor. Arranged between the upper ends of the frame members 1 is a heated roller 2 of the mangle the journals 3 at the respective ends of which are rotatably mounted in bearings.L

providedtherefor in said frame members 1. Provided upon one of the journals 3 is a gear fl which meshes with a pinion 'iixed to a stud shaft/rotatably mounted in the' corresponding frame member 1. 4Also pro- `vided upon thegsdhait Gis al worm` wheel 7,

which' meshes withV a worm' 8 formed upon s liattt) mounted as shown in bearings provided upon thekouter side el the corresponding frame members l'. Also carried by the shaft 9 isa channelv pulley 10 through the .medium ofwhi'ch, when the machine is in use, driving of the machine is effected, a bel-t being adapted to travel around said pulley and connect with the source of-power.

Arranged around theheated roller 2 is a plurality of movablel or padded rollers 11 the journal-s 12 of which are rotatably mounted in bearing blocks lwhich are slidably mounted in slots lll provided in the' frame members l which are disposed ra-A dially relative tothe axis of roller-'2. Cooperating with said movable rollers vare helical compression springs 15 the inner ends of which engage against the outer sides of bearing blocks 13, the outer ends of said springs being positioned in' housings '16 and being engaged by .adjusting screws 17 where-l by the tension of said springs may be reguf lated. The springs 15 evidently serve to normally h'old the rollers 11 in operative positions that is in contact with the periphery of rollerV 2, outward movementof said movable rollers beingagainst the influence of said springs. Provided at corresponding ends of the rollers 11' are pinions l8which mesh with the gear 4, an'operative connection being thus established between the heatedand padded rollers whereby simultaneous rotation thereof will be eiiected upon driving orrotation of the pulley 10.

Arranged within the. heated roller is the us ual tubular fuel burner 19 which, when the device is in'use, is connected with any suitable source of fuel supply, the flames 'for jets which are supported by the fuel issu- 'ing from said" burner serving to heat the roller 2.- j V At the' front side of tlfejmachineiis-provided 'the usual table v20"'r'om Awhich the articles to be ironedare fed to position between the rollers 2 andl 11, theJ upper side of said table being substantially tangential with the'periphery ofroller `2.

Coperating with each the bearing blocks 13 of the padded rollers lare toggles 21the-fouter endsof which loosely engage recesses 22 provided at the under or inner sides of said bearing blocks. 'The inner ends of said tog-gies are pivotally secured 'at 23 to the frame members 1, the'respective extremities of said toggles being positioned in Planes passing through the axes of said heated and movable rollersso lthat when said toggles are in extended or straightened positions, the same will be locked on dead center. Further, the arrangement is such that when said toggles are actuated or straightenedas just mentionedthe padded rollers l1 will be moved outwardlyT from engagement with the heated roller and will be lockedin their outward positions by the locking of .said toggles upon dead center.

The knee joints. of the toggles at opposite endsof the mangle engage notches or slots 24 provided in the periphery of a circular member' 25 which is rotatably mounted upon an 'extension of thebearing for the journal 3 of the heated roller at the corresponding end of the machine. The arrangement is such that, upon clockwise oscillation of the member 25, the toggles 21 will be simultaneously .actuated or straightened to cause outward movement of the padded rollers as justdescribed. In order to lessen friction rollers 26.are preferably provided at the knee joints of the'toggles for engagement with the sides' of the notches24 in this operation.

Depending from the actuating members 25 are arms 27 with which engage links 28 connecteda't their forwardiends with rocker arms 29' depending from a rock shaft 30 the extremities of which are mounted in frame members 1. "Ifhus the actuating members 25- at the opposite' ends of the device are connected for simultaneous movement and so that, when the rock shaft 30 is oscillated,

both ends of the padded rollers will be correspondingly moved. Provided at one end ofthe shaft 30-is an upwardly projecting yhandle or lever 31 whereby said shaft may be manually rocked to effect the `desired movement of the padded rollers.

With the arrangement set forth, it will be seen that in the operation of the mangle,

- in the event of the rollers ceasing operation,

the padded rollers maybe readily and expeditiously'movedfout of engagement with the heated roller by sim ly rocking the lever 31.". Through the luse'o toggles,lgreat lever-v age results-and' so that rocking of the leverclaim as new and desire to secure by Letters Patent is:
